Thejas M Nair updated HIVE-15717:

Summary: JDBC: Implement rowDeleted, rowInserted and rowUpdated to return
false (was: Class "org.apache.hive.beeline.Rows.Row" constructor is CPU
consuming due to exception handling)

>
> In performance profile of beeline with hive jdbc driver, it is seen that lot
> of time is spent in Class "org.apache.hive.beeline.Rows.Row" constructor, due
> to exception handling.
> The exception handling from the 3 methods calls (rowDeleted, rowInserted and
> rowUpdated). The implementation of these methods in
> org.apache.hive.jdbc.HiveBaseResultSet class is just throwing
> SQLException("Method not supported”), i.e. no real implementations.
> Implementing these methods to return false instead of throwing exception will
> help improve the performance.
